objectives

NEWINorth East Wales Institute of Higher Education

OBJECTIVES
  • Develop a Home Automation Remote System
  • Use different inner and outer network technologies
  • Use devices that are easy to install
  • Use low-price materials and devices
  • Make it suitable for inexperienced users or even disabled people
  • Make it scalable for further add-ons
  • Manage multiple control points
  • Encourage standardization
why remote control

NEWINorth East Wales Institute of Higher Education

WHY REMOTE CONTROL?
  • Enables control from almost anywhere (more comfortable)
  • Instant alerts greatly increase security
  • Backup emergency control
  • Optimal for people with reduced mobility
  • It can be combined with local control to give higher flexibility.
  • The network hierarchy has been rapidly moving lower in the chain towards smaller and more personal devices (Canosa, 2001)

X-10
  • Technique “Power Line Carrier”
  • Frame sent two times
  • Noise filter / Phase coupler
  • Up to 256 controlled devices

GSM
  • AT / AT+ commands
  • Serial connection
  • SMS
  • MMS
  • Dials

INTERNET PROTOCOL
  • Control Points
  • IP devices
    • IP cameras
  • Web browsers
  • XML
  • Siemens UPnP Stack
    • Addressing
    • Discovery (SSDP)
    • Description (XML)
      • Control (SOAP)

interfaces middleware

NEWINorth East Wales Institute of Higher Education

INTERFACES & MIDDLEWARE
  • Middleware
    • Standard compatible
    • Link technologies (translation)
    • Robust
  • User interfaces (Local & Remote)
    • Must follow Heuristic Evaluation (Molich and Nielsen 1990)
    • High usability
      • Good visibility of system status
      • Match between system and real world
    • Error prevention (minimize error messages)
    • Aesthetic and minimalist
    • Help
conclusion

NEWINorth East Wales Institute of Higher Education

Conclusion
  • The E-home is coming quickly
  • Standards are not completely established
  • Remote Control is necessary for certain purposes
  • Developing low-price systems will accelerate the process of turning our homes intelligent
  • The price of the “intelligence” in a house in comparison with its “body”, is insignificant
